Abstract
For 2D Navier-Stokes equations defined in a bounded domain Ω we study stabilization of solution near a given steady-state flow \( \hat v(x) \) by means of feedback control defined on a part Γ of boundary ∂Ω. New mathematical formalization of feedback notion is proposed. With its help for a prescribed number σ > 0 and for an initial condition v 0(x) placed in a small neighbourhood of \( \hat v(x) \) a control u(t, x′), x ∈ Γ, is constructed such that solution v(t, x) of obtained boundary value problem for 2D Navier-Stokes equations satisfies the inequality:
